Granted: 1992-08-18
Abstract: ABSTRACT OF THE DISCLOSURES          An automatic gain control device for use in an optical memory device has  a  circuit  for producing an amplification control signal which is fedback to a gain control amplifier through a sample-hold circuit.  A pulse train detection circuit is provided for detecting the pulse train indicating that the data stored area on the optical memory device is being playbacked.  When the pulse train is detected, the sample-hold circuit is made inactive so that the amplification control signal is directly fedback to the gain control amplifier, and when the pulse train ends, the sample-hold  circuit   is  made   active  to  hold  the amplification control signal obtained at the end of the pulse train and to produce the amplification control signal held in the sample-hold circuit.

Abstract: A method of controlling the pulsing of a granular medium filter (1) is provided bases on determination of the rise rate of the liquid level in the filter tank (3) above the filtration medium (1). A pulse system is activated whereby a pulse, in which sub-fluidizing flows of a fluid are directed upwardly through the filter medium (1) from an array of orifices (7), is initiated whenever the determined liquid level rise rate attains a predetermined value. The pulse flows dislodge solids from the upper surface (11) of the bed (1) and cause a portion of the solids to be stored within the bed itself at particular loci, thus decreasing the resistance of the bed and reducing the liquid level rise rate. The frequency of backwashing needed is accordingly optimized over a wide range of solids load, liquid load and other factors affecting the filtration. Backwashing may be initiated after a predetermined number of pulses, after a preset filtration time has elapsed, or when the level of liquid in the tank (3) reaches a preset high value (25).

Abstract: Abstract of the Disclosure:        In a high-speed packet multiplex communication network including a transmission line with a predetermined bandwidth and accommodating a plurality of information sources, the sources having various packet i delivery rates over a range of between a peak rate and a lower rate than an average rate and demanding various transport performances, the sources are preliminarily classified into a plurality of types according to transport performances required and different transmission priorities are assigned to the different types, respectively.  Bandwidths of sources of first priority and second priority are determined ones corresponding to the peak rate and the average rate, respectively.  A virtual bandwidth may be calculated for the second priority source as a value between the peak and average rates.  In response to connection requests from the sources, each of the connection requests is admitted when a bandwidth defined by the priority of each source is accepted in a residual bandwidth of the predetermined bandwidth, and the packets from the source of the first priority are preferentially transmitted to the transmission line, packets of the second priority  source are transmitted when packets of the first priority source are absent.  Thus, high bandwidth efficiency is insured while the high transport performance of the first priority source is maintained.
